HU227407B1 - Hinged frame for posters or the like - Google Patents

Abstract

The invention relates to a frame for posters or the like comprising a basic frame with front elements fitted to its edges. The front elements are connected in each case to the basic frame by a joint and swing out individually from the surface of the frame. Each of the joints presents a cup and a pin. In order to reduce assembly and production costs of a frame and obtain substantial improvement of its stability, the joint cup (9) and the joint pin (10) are both designed on a section (7), one of the sections (7) presenting a catching element (17) which bites elastically into the other section in a substantially arc-shaped area in which at least one catching recess (19) is provided.

Description

Frame for placing posters or the like

The present invention relates to a frame for displaying posters or the like. This frame has a base frame, and at its edges are fixed at the forehead, which are connected by a joint to the base frame, and which can be folded out of the frame surface individually. Each wrist has a hinge and a hinge pin that can be inserted into the hinge. The wrist cup and the pivot pin are each formed on a profile member. One profile member has a latch member which is resiliently supported on the other profile member with a substantially circular surface, wherein at least one latch recess is formed.

Such a frame is known, for example, from German Patent Application Laid-Open No. 32 32 521. The front members of this frame are provided with a longitudinal groove on the inside. One edge of a leaf spring extends into it, the other edge of which extends into a groove in the base frame. Several leaf springs are spaced along the length of the homick element. When the homick element is rotated, the slightly curved leaf spring tilts through its dead center so that the homick element secures it securely both in the closed position and in the folded out position.

It is an object of the present invention to reduce the manufacturing and assembly costs and significantly increase the stability of the frame described in the introduction.

According to the present invention, this object is solved by providing the pivot pin with a longitudinal groove delimiting two elastic stem sections and an expanded portion of the longitudinal groove into which a rod of circular cross-section can be inserted.

Leaf springs are not required in the frame of the invention. The locking elements acting on each of the abrasive surfaces together with the associated locking elements ensure that the front elements are kept in a closed or folded position without leaf springs. The absence of leaf springs reduces production and installation costs.

Due to the elastic stem sections of the present invention, the hinge pin can be compressed to some extent when inserted into the hinge cup. This increases the circumference of the pivot pin that the wrist cup encircles.

In the foremost embodiment, a particularly secure connection between the pivot pin and the pivot pin is achieved when the pivot of the pivot pin has an expanded portion into which a rod of circular cross-section can be inserted. At this point, at least three protruding points of acute cross-section are formed on the inner side of the pivot section of the pivot pin, which are evenly distributed around the inner circumference of the pivot sections. Sharp-angled protrusions facilitate the insertion of a circular bar into the pivot pin by reducing the contact area and thereby friction between the circular bar and the pivot pin.

In a further preferred embodiment of the frame according to the invention, the front sections are releasably secured to the respective pivotable profile members. This allows the frame to be provided with different front and back colors and / or shapes, so that the frame can be optimally adapted to the particular mounting environment.

In yet another preferred embodiment of the frame according to the invention, the forehead and / or profile elements can be locked against unauthorized opening of the frame.

Figures 3 and 4 show separately the joint of the section sections forming the frame according to the invention.

The frame of the present invention consists of a basic frame which is composed of four ohms part 1. The two side portions are substantially parallel to each other. The lower side part consists of a rectangular tube 1 and a square 2, which are laid down on top of one another by a hot stone 3. The rectangular tube 1 forms a step with the square tube 2 on which a hat section 4 is fixed. The cap 4 is flush with the square tube 2, the 4 weeks 2 and the cap 4 carry a sheet 5 which, with the L-section 3, forms a trough for receiving posters or the like. The 3 L-section

φ * at the same time protects against dirt caused by dripping glue (so-called glue tray).

On the outside of the L-section 3, a double-curved profile member 6 is secured, to which a second front member 8 is hingedly connected via a second prof 7 member 1.1. The wrist comprises a channel-shaped articulated joint $ into which a pivot pin 10 is inserted. The pivot pin 10 is provided with a longitudinal groove 11 which forms two elastic leg sections 12 and 13. The longitudinal groove 11 has an expanded portion 14 having a three-pointed rib 15 on its inner side. The ribs 15 are uniformly distributed on the outer circumference of the circular cross-sectional rod 10, which is inserted into the longitudinal groove 11. ₍

The profile member 7 is integrally formed with an arcuate longitudinal shank 17, which acts as a locking member and resiliently attacks a pivot portion 18 of the profile member δ on the hinge cup. The abutment surface 18 has a locking recess 19 into which a longitudinal leg 17 of a protruding member 7 is protruded when the front flap 8 is unearthed (see FIG.

When closed, the front members 8 are protected against unauthorized opening (not shown; by locking, for example in the form of a lock or a special tool pivotable strap which, when closed, extends beyond the projection on the base frame.

The profile member 7 has a substantially flat support surface 20 on which the front member 8 rests on a suitably flat wall section 21. The bracket 8 is a hollow body which is internally reinforced with a plurality of cross bars. To fasten the front member 8, see FIG

The profiles of ΦΦ * Φ> * ® are provided with a flange-like longitudinal edge 22, which is surrounded by a groove 23 of the forehead 8. The profile member 7 is further provided with a recessed groove 24 in which fasteners (not shown) for fastening the respective front flange 8 can be releasably secured.

The corner edges 8 in the corner of the frame are connected by corner elements (not shown). Alternatively, the retaining elements 8 and the profile elements 6, 7 may be inclined at the corners of the frame.

To provide high stability and long service life of the frame according to the invention, the profile elements E, 7 are preferably made from an alloy of> 1-Mg-Si. The A. 8 foreheads, however, are preferably made of plastic so that different color and shape variations can be achieved inexpensively.
